Why does DraftSight always goes to default (Examples) folder while opening drawing file?

This behavior is controlled by system variable named REMEMBERFOLDERS. This variable controls the path to be displayed in standard file selection dialog boxes.

0   Default path (C:\\ProgramData\\Dassault Systemes\\DraftSight\\Examples) is used for all standard file selection dialog boxes.

1   The last path used in that dialog box will be used for all standard file selection dialog boxes.
